Dynamic Guide Color: This color well sets the color for dynamic guides.

Safe Zones
Safe zones are special guides to help you avoid putting layers in areas of the screen
that might not appear correctly on consumer television sets. Layers that appear outside
the action safe region may be cut off. The area outside the title safe region may have
distortions that make text hard to read. The safe zone guides can be turned on and off
in the View menu, or in the View pop-up menu at the upper-right corner of the main
window (above the Canvas).
Action Safe Region: Sets the percentage of the Canvas where the action safe guides
appear.
Title Safe Region: Sets the percentage of the Canvas where the title safe guides
appear.
Safe Zone Color: Sets the color of the safe zone guides.
Film Zone
When producing output to be used for both television and film, it may be helpful to
see the area of the TV frame that will be cut off when it is converted to film. The film
zone settings allow you to display a guide that identifies the aspect ratio of the film
gauge you are working in. Film zone guides can be turned on and off in the View menu
or in the View pop-up menu at the upper-right corner of the main window.
Aspect Ratio: This pop-up menu sets the guide size to match one of the standard
aspect ratios or lets you enter a custom value.
To choose an existing aspect ratio:
m Choose a setting from the Aspect Ratio pop-up menu.
To create a custom aspect ratio:
m Type a number representing the screen width (based on a height of 1) into the value
field to the right of the pop-up menu, then press Return.
Custom is automatically chosen from the Aspect Ratio pop-up menu.
Film Zone Color: Sets the color of the film zone guides.
Snapping
Objects in the Canvas automatically snap to other objects when you drag them around.
This setting determines whether the objects snap to objects’ center points, edges, or
both centers and edges. Snapping can be turned on and off in the View menu or by
pressing N when the Canvas is active.
